Looking for an old mount for a bargain price.  Any of you guys that
converted to long legs have a short leg mount you want to part with for a
salvage price?  I'm working on an engine stand project and need a dynafocal
1 mount preferably for an RV-4.

Located in Portland, OR, so closer is better but I'll consider anything
within reasonable shipping distance.

No need to reply to the whole list, email me back directly.

Do not archive

Thanks,

Mike,
I bought my RV-4 mount about 2 years ago - do I have the short or the long legs?  How do I know, ie., how long are the 'short' and how long are the 'long'?

Thanks,
Ken Powell


You've got the long legs.  I don't have measurements for the difference between the two.  I think the original was designed to accommodate a 70" prop and the later revision will accommodate a 72".  This is in order to have a certain ground clearance as specified by Van.  I think it's 6" when the fuse is level.

You have to go back to about the mid 90s to find the short legs.  The long legs were a revision to accommodate longer props on 180 hp engines.  The original RV-4s were designed for an O-320, not an O-360.  Then all those old ex-hot-rodders got into building airplanes...
